Abstract: In accordance with the present invention a scouring pad and/or scrubbing pad which can be constructed out of a variety of different materials and configurations contains an internal pouch or pocket that can be utilized by inserting a rigid object or scraper (which may or may not have a handle) into the pouch or pocket of the scouring or scrubbing pad. The rigid object can be removed from one scouring pad and reinserted into another scouring pad to meet the needs of multiple types of surfaces being cleaned.
